DEVICE FOR CONTAMINATION-FREE DELIVERY AND DISCHARGE OF LIQUID

摘要

The invention pertains to a device for contamination-free delivery and discharge of liquid into and out of a reaction vessel (15), having a tube (1) one end of which forms a connecting piece (2) to a pipette or the like and the other end of which has a first aperture (3). To avoid contamination when the reaction vessel is filled with or drained of liquids, the invention proposes that a second connecting piece (4) communicating with at least a second aperture (8) be provided near the first end.
